Hi David
So could you tell me the different between normalize and amplify? I usually
do normalization to adjust the amplitude to 0db, and I know this removes dc
offset if any. So are there any different?
Thanks in advance
Cuong

Hi Rich,
although amplification and gain do roughly the same thing, there are some
differences.
The gain of track is applied to the whole track, and is only applied when
the track is mixed for playback or export to a file, or when you use the mix
and render command. Changing the gain, doesn't affect the amplitude of the
audio data in the track.
The amplify effect can be applied to a time range in one or more tracks. It
changes the amplitudes of the audio data in the track, and it ignores the
gain settings of the tracks.
If you select one or more tracks and choose mix and render on the tracks
menu, then in the resultant track, the gains of the tracks have been taken
into account, and the gain of the track is initially zero.
So for example, if you select a single track, set the gain to 3, apply the
mix and render command, the gain is applied to the audio data in the track,
and the gain is reset to zero.
David.

Is there any difference between increasing the volume of a track through
the amplify selection in the Effects menu, and by pressing shift-g for
gain and entering a number? If there is a difference, what is it?
Also, when I have a project of several tracks that are all unselected,
and then I record another track, select it, and check the level of that
last track in the amplify selection in the Effects menu, it always seems
to show a negative number no matter how quiet that last track is. Why
is that? Also, merely making this check on the selected last track
seems to make every track selected. What is going on?
